I have been reading around on the forums tonight looking for the best way to upgrade the speakers in my daily driver. The car is a ford probe and currently it has a blaupunkt kingston (http://www.sonicelectronix.com/item_10294_Blaupunkt+Kingston+MP47.html) head unit and some old blaupunkt speakers, one of which has croaked. No subs or amplifier. I have a pair of 6.5's in the doors and 6x9's in the rear and I am thinking of upgrading to a pair of good 6.5's up front and losing the rear speakers in favor of a small subwoofer and amp, probably a single 12".

The speakers I have in mind for the doors are the ever-recommended Pioneer REV TS-D161R. I want to run those with just my head unit and re-use my blaupunkt speakers in the rear until I have the money//come across the right sub and amp.

Am I heading in the right direction? I don't need a ton of bass or have hundreds to spend but this combination should be better than what I have currently if I did my reading right.
